Frequently Asked Questions
Q: Are these injectors brand-new?
A: Yes—this set is new, not remanufactured.
Q: What turbo/tune should I pair with 150% overs?
A: A larger single or compound setup and custom tuning are recommended to manage EGT and smoke while realizing the added fuel.
Q: Do I need a lift pump?
A: Absolutely. A quality lift pump ensures stable supply pressure and filtration at elevated flow. See our lift pump options.
Q: Will these fit late 2004.5–2007 trucks?
A: No—this set is for 2003–2004 (early) common-rail only. Late 2004.5–2007 use different injector part numbers.
